17 Claims.

This invention relates to machines bywhich fastenings are driven to eiiect the connection of Work-pieces. 'Machines of this character may be employed for the attachmentto shoes of heelparts, as bases and lifts of rubber or the like. The present case is a division of anapplication led in my name in the United States Patent Oiiice on December 12, 1942, and bearing they Serial No. 468,774. A second divisional application, directed to the guard-plate for the quills of the die, was Ai'lledA in myname on July 12, 1944, with the Seriall Number 544,495.

In fastening-inserting machines, an inserting die having fastening-receiving passages and a driver or driver-assembly'co-operating Withthe die-passagesfare arranged for removal and replacement in the machine vto provide for dilerent inserting designs. For the operation rof the machine, the die-passages and drivers must be in registration. An object of this invention is to make certain that the die and driver or drivers match or register, so the drivers'will enter and operate correctly in their passages.' This' is brought about by preventing the completion of a certain act on the part of the operator, until the inserting designs Iof the die-passages and drivers match and both thedie and drivers are fully in place. Preferably, a testing member is only movable by the operator into position in preparation for the operation of the machine when such matching or registration ofthe elements exists. There is shown herein means for preventing operation of the machine until the testing member is positioned in this manner. This member may be a bar variable in position upon a shield or closure for the inserting mechanism, vit engaging the fastening-inserting elements and preventing closure unless these match, in which case it, enters depressions in them. l The shieldmay also engage securing means Which hold the inserting elements in registration and'similarly prevent closing the shield and vsubsequent starting Vof the machine until the positioning and securing *is complete.

The shield or closure, in its control ofthe operation of the machine, preferably prevents movement of a member through whichsaid machine is started.

La Chapelle, July. 16, 1940, these', machinesgbeing designed for the attachme'ntpf kheel-basesand top-lifts to shoes. In apparatus of this character, there is mounted upon a frame l0 a die-block .|2, in which are vertical passages I4 `to receive the fastenings to be inserted'. These passages may include a multiple ofv all the designs which are to be employed. The die-blockis shown as separably mounted in place byscrews 1 6 threaded vertically into the frame.A The portion of, the

die-block with which the work contacts Vis provided by a plate I8, carried in ways 2ll*atA the` underside ofth e die and latched in place by a y spring-plunger 22, movable through said die and y entering an opening at the front of the plate.

The passages through the plate, corresponding to those of a particular nailing design in the die, terminate in depending quills 24. The quills enter the surface of a rubber or otherelastic lift block 30 to the die-block-passages I4. vThe'insertion of the fastenings in the work is effected by. a

gang of drivers 34, which may first act as awls, as inthe previously mentioned La Chapelle patent. c These drivers are xedin a plate 36 carriedbya 1 OFFICE able in said top-girtfand received in a vdepression with the movement.

An inclined surface |58 at the forward extremity of the member serves, by contact of the plungerr with it, to liftthis as `the door approaches closure, said plunger entering a latching depression |60 in the retaining member when the door is fullyclosed.

' Assume that them'achine of this invention isy to be employed for the attachment to a shoeof a heel-base I-I and an elastic lift T, by fastenings cut from strings .F of ber and driven through pricked openings in said lift and `base, and that I it is necessary to change the inserting design. 'I'he door` H0, which has been closed during the preceding operation,-isv freed from thelatch |54 and opened. The operator then releases the driver-assembly by withdrawing the plunger 44, and removes, it, and similarly frees the quillplate I8 from the plunger 22 and takes it from the machine. He, thereupon, selects another pair of these fastening-inserting elements arranged in accordance with the `chosen design, and inserts them in their respective ways 42 and 20. With the inserting elements properly matched and fully positioned, their respective depressions |24 and |26 will register or be in vertical alinement, and the door maybe closed, its barportion |22 having been adjusted tothe correct transverse position to enter these depressions. Further, if the new pair of inserting velements has been fully seated in their ways, their latches f 44 and 22 will have engaged the respective depressions in the driver-plate 3S and the quill-l plate 8, and will be out of the path of the door-projections and |28. Therefore, the closure of the door is not interfered With in this respect, and when fully shut and secured by the the work for the inserting operation. As pres-l sure is applied, the plate |00 yields against the springs |06 and the quills are seated in the substance of the lift to compress the elastic material.

The operator d-epresses the lever |38, freed by the full closure of the door 0, to trip the driving clutch. A power-cycle of the machine is thereupon performed, the loader-block 30 severing a group of discrete fastenings from the strings F and delivering them above the die-passages I4 to be inserted in the Work by the drivers 34, which have previously been actuated to prick openings to receive these fastenings. The shoe with its attached base and lift may now be freed for removal from the machine.
